Fussilat 41:5

They say, “Our hearts are covered against what you are calling us to; there is deafness in our ears, and there is a barrier between us and you. So carry on [in your way], we will carry on [in our way].”

And they say, "Our hearts are within coverings [i.e., screened] from that to which you invite us, and in our ears is deafness, and between us and you is a partition, so work;[1383] indeed, we are working."

[1383] For your own religion or work against us.

5. And they say: "Our hearts are under coverings (screened) from that to which you invite us; and in our ears is deafness, and between us and you is a screen: so work you (on your way); verily, we are working (on our way)."

And they say: Our hearts are protected from that unto which thou (O Muhammad) callest us, and in our ears there is a deafness, and between us and thee there is a veil. Act, then. Lo! we also shall be acting.
